Today we spent quite a bit of time on a lab in the effort to try to better understand acceleration. We will be spending quite a bit more time on acceleration in the coming weeks as it is key to much of Newton's Laws.
Homework for this week is:
Make the following graphs:
1. Velocity vs. Time graph for the higher slope and one of the spheres.
2. Acceleration vs. Time graph for the same slope and sphere. (Please use graph paper for both of these graphs.)
Using those graphs answer the following questions.
1. At what point on the ramp did the ball have the highest speed?
2. What would you estimate the speed of the ball to be if the ramp was long enough to allow the ball to travel for one more second.
3. What was the average speed of the ball for the entire ramp?
4. When was acceleration greatest or was it constant?
5. If it wasn't constant….why not?
6. What was the average acceleration of the ball for the entire ramp?
7. What would the acceleration be if the ramp was long enough to allow the ball to travel for one more second. (Estimate this using your graph.)
